i have a nautic logic gps upgrade kit for an 07 x star that plugs into the paddlewheel and uses the 4 pin gray conneter the paddle wheel is airman but there 2 possible connectors so check yours before buying this kit. i went to full stargazer module on the boat it works great with the prefect pass but stargazer gets gps signal faster the nautic takes a 5-10 seconds to acquire signal at start up. its was used for 20 hrs last summer i wanna get $225 shipped to the lower 48 paypal only all install info comes with the system it has the swift 10hz receiver i can provide pics if needed

Look at http://www.nauticlaugic.com/nl4.html. It has a "by boat guide". It's simply is plugged in place of the paddle wheel. The different models are basically different connectors (triducer vs spd/temp). Google "nautic logic gps" and you will also see some reviews over on wakeworld.

It's a NL4-Mc it's a GPS replacement for the paddle wheel plugs inline and works well its not a prefect pass system it will work on some later 08 models had the same airman transducer u need to check your connectors to be sure
